Wacker Neuson 1000018400 6-Point Screw M6x20 8.8 DIN933

The Wacker Neuson 1000018400 is a genuine OEM 6-Point Screw M6x20 8.8 DIN933 designed for the WL50 Articulated Wheel Loader and TH627 machines. As a factory-sourced fastener, part 1000018400 meets the exact grade and dimensional specification called out in the Wacker Neuson parts documentation, ensuring a correct and secure fit at every installation point. Sourcing the correct DIN933-standard screw matters — substituting an incorrect grade or thread pitch can compromise joint integrity and lead to premature fastener failure in demanding work conditions.

Key Features

• Certified Grade 8.8 Tensile Strength — Manufactured to DIN933 Grade 8.8 specification, delivering the minimum yield and tensile strength required for structural and mechanical fastening applications on compact construction equipment.
• Full-Thread Hex Configuration — Six-point M6x20 full-thread profile ensures consistent torque transfer and even clamping load across mating surfaces without thread stripping or cam-out.
• Verified Fitment for WL50 and TH627 — Confirmed for use on the WL50 Articulated Wheel Loader (Cab) and TH627, matching the exact part number referenced in Wacker Neuson official parts documentation.
• Genuine OEM Sourcing — Supplied directly through the Wacker Neuson OEM parts network, ensuring the correct alloy grade, thread tolerance, and head geometry specified by the original equipment design.
• Direct Hardware Replacement — Installs as a drop-in replacement at any M6x20 fastening point on applicable machines, with no additional hardware or modification needed to achieve proper seating and torque.

A DIN933 hex screw is a fully threaded metric fastener conforming to the German Institute for Standardization specification for hexagon head bolts. On equipment like the WL50 Articulated Wheel Loader and TH627, fasteners of this grade are used at critical structural, panel, and mechanical attachment points where consistent clamping force is essential to safe and reliable machine operation. When a fastener of this type fails — through corrosion, thread damage, or incorrect grade substitution — the joint it secures can loosen under load, potentially causing component misalignment, noise, or mechanical failure. Replacing with the correct OEM-spec part restores the designed clamping integrity to that connection point.
